随着科技的发展、社会的进步、人们生活水平的不断提高,人们对信息消费的多元化需求日趋明显,传统的模拟信号移动电视及模拟音频广播已经越来越不能满足大众的使用需求。而随着数字广播电视技术、互联网技术和多媒体技术应用的不断创新,人们已经可以通过广播电视覆盖网开展移动多媒体业务。2006年10月,国家广播电视总局正式颁布了中国移动多媒体广播标准CMMB,这是由我国自主研发的,具有完全自主知识产权的移动多媒体广播标准。现在CMMB已经实现了从发端到终端的产业化,系统的覆盖组网正在按计划稳步推进。本文试图就CMMB技术及其发展前景进行一些分析。
With the development of science and technology, the progress of society and the continuous improvement of people’s living standards, people’s demand for diversified information consumption has become increasingly evident. The traditional analog signal mobile TV and analog audio broadcasting have increasingly failed to meet the needs of the general public. With the continuous innovation of digital broadcasting and television technology, Internet technology and multimedia technology application, people have been able to carry out mobile multimedia services through the radio and television overlay network. In October 2006, the State Administration of Radio, Film and Television officially promulgated China Mobile Multimedia Broadcasting Standard CMMB, a mobile multimedia broadcasting standard developed independently by China with independent intellectual property rights. CMMB has now achieved from the terminal to the terminal of industrialization, the system coverage network is steadily advancing according to plan. This article attempts to CMMB technology and its development prospects for some analysis.
